I was reading Krishnan Subramanian's post, Two Events That “Clouded” Our Thinking In 2011. The thing that caught my attention was Krishnan's comments on why PaaS is a superior alternative to DevOps: The shift in the thinking about the enterprise...
Are you Really using the Fastest and Most Scalable Cache with your Application? We are hearing lately reports from several accounts "discovering" that Terracotta ehcache is not the fastest and most scalable cache out there. GigaSpaces local cache actually performs much better. With the benchmark results below we see GigaSpaces [...]
I recently read a book called: "Physics of the Impossible" by the theoretical physicist Michio Kaku. Dr. Kaku lists "Possible Impossibilities" and classifies these into different categories where all these "impossibilities" may happen in the near/distant future. When talking about "zero latency", I consider this something we can achieve today. The [...]
Our best practices wiki is growing rapidly and full with good and useful material. Here are few new best practices added lately: - Finding Partition Load – routing data based on partition load. - Even Data Distribution – simple example explains how to evenly partition application data. - WAN Replication Gateway – Simple blueprint for WAN replication scenario [...]
I just published "Considering Datastores" in the "articles" section of my blog, a piece discussing various data storage mechanisms and their strengths and weaknesses compared to each other.
Usually you index and execute queries using primitive fields (long, float, string, etc). The fields may be within the root level of the space object, or embedded within nested objects within the space object. You may construct a query using a template object or SQL to specify the criteria you [...]
The Master-Worker Pattern (sometimes called Master-Slave pattern) is used for parallel processing. It follows a simple approach that allows applications to perform simultaneous processing across multiple machines or processes via a Master and multiple Workers. In GigaSpaces XAP, you can implement the Master-Worker pattern using several methods: - Task Executors [...]
GigaSpaces XAP 7.0 was released in mid-July. For those who missed the buzz, in this post I’ll try to provide a summary of the main perspectives that were voiced about the new release. At the end of this post is...
During the past few weeks I gave few talks about our latest XAP release and some of the new models that we introduce in this new release. During all those talks I found myself explaining what is the difference between...
This year JavaOne will include really cool lab - PetClinic in the Clouds: Scaling a Classic Enterprise Application. In this Hands-on Lab, participants will take a popular Web application (the Spring PetClinic sample application) and modify it so that it can be deployed on the Amazon EC2 cloud computing infrastructure. [...]
I was very pleased to read an email from Leonardo, who was the winner of the OpenSpaces Developer Challenge (a worldwide programming contest using the Gigaspaces application server which was held last year), saying that he is now a finalist...
MuleSource is a rather popular open source ESB implementation. What I particularly liked about it when I first saw it is how simple it is to glue different services that are communicating in different protocols in a very simple way...
Introduction Over the past several years highly concurrent applications have faced some serious challenges when trying to scale on multi core machines. GigaSpaces scale-out-application server aims to solve this problem by freeing the user from dealing with the need to handle concurrency while building his distributed application. For the last [...]
I’ve been reading this nice post from Daniel Gradecak's blogs. He is asking interesting questions about how architects building their systems and how JavaSpaces and SBA are used when designing distributed systems. See my comment as a feedback to his questions. Thank you Daniel for this post! Shay
This week i got a nice xMas surprise hearing that we won the Best Cloud Application Provider category in the The 2008 Cloudies AwardsWhat makes it even sweater is knowing that it came from one of the best cloud bloggers...
